7,457,298 | 0 | Why is the NTOSKRNL.exe IMAGE_MACHINETYPE header field set to x86 on only certain editions of Windows 7 x64? <p>I am using windows 7 home premium x64. I was wondering why exactly the IMAGE_MACHINETYPE field in the header of ntoskrnl in my system32 directory specifies x86. IDA will even let me disassemble it as native x86.</p> <p>Yet on my windows 7 pro machine, image_machinetype is x64. Am I just missing something.. or why is ntoskrnl 32 bit on a 64 bit OS?</p> |
36,208,800 | 0 | Azure Web App Deploy via FTP Credential not Working <p>I have built a web app in ARM (new Portal) with the SDK, and downloaded the Publishing Profile XML file. Inside it has an FTP element with attributes for FTP user name and password. I can log in with those credentials but not upload files - access denied. I cannot delete the hostingstart.html file either. Getting a "dir" on the FTP site works, so I know my credentials are being accepted.</p> <p>I can see in the Portal GUI that there is an FTP user name, but I do not know its password and it does not match what is in the Publishing Profile XML.</p> <p>I am trying to provision a brand new web app with the SDK and upload local-built content, completely unattended. How can I make this happen?</p> <p>Thanks.</p> |
32,283,319 | 0 | How to get and change a variable in my view controller from SKScene <p>Ok so here is the code</p> <pre><code>class GameViewController: UIViewController, SceneTransitionDelegate, GKGameCenterControllerDelegate, ADBannerViewDelegate { var coolbool:Bool = false ...abunch of unimportant stuff functions and stuff } </code></pre> <p>And here is what I am trying to do from my SKScene</p> <pre><code>func thing1() { let controller = GameViewController() controller.coolbool = true println(controller.coolbool) // Will say that it is true sceneDelegate.transitionToScene(Menu.self) //Menu.self is the skscene that we used to be in and will be in } func thing2() { println(controller.coolbool) // Will say that it is false if (controller.coolbool == true) { //Put rainbows over every sprite and change generator settings } } </code></pre> <p>So basically what happens is that "coolbool" is initialized as being false. Until thing1() is called causing the variable "coolbool " to change. And i confirm its change immediately after, before the transition. However after the transition (to the same scene (I'm trying to make it look different if the bool is true)) if you ask what the value is, it says its false.... even though i just set it to true.</p> <p>Anyway I assume I am doing something wrong, is their a better way to do this??? Incase you want it here is the transition function</p> <pre><code>func transitionToScene(sceneClass:Scene.Type) { playing = false var sizeRect = UIScreen.mainScreen().applicationFrame var width = sizeRect.size.width * UIScreen.mainScreen().scale var height = sizeRect.size.height * UIScreen.mainScreen().scale let skView = self.view as! SKView let scene = sceneClass(size: skView.bounds.size) scene.size = CGSizeMake(width, height) rwidth = width rheight = height swidth = width sheight = height skView.ignoresSiblingOrder = true scene.scaleMode = .AspectFill scene.sceneDelegate = self skView.presentScene(scene) } </code></pre> |

Which is why the general rule is not to use USSD for anything in Android- not only is it not portable across carriers, but there is no real USSD API- you can just sort of kind of hack some of it together (not to mention that USSD is a hack itself that should die now that web services and data connections exist).</p> |

36,627,761 | 0 | Adding wait method to a JTable <p>Edited - To clarify what my problem was I have decided to edit this. </p> <p>My problem involved the method below:</p> <pre><code>addTransactionButton.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent ae){ AllGUI allGUI = new AllGUI(); allGUI.createAllGUI(); TCRSpecificGUI tcrGUI = new TCRSpecificGUI(); tcrGUI.getNtryName(); dtm.addRow(new Object[]{TCRSpecificGUI.ntryName,AllGUI.bankTransCode,TCRSpecificGUI.endToEndId, AllGUI.transAmount,AllGUI.initiatingPartyId,AllGUI.initiatingPartySchemeName, AllGUI.debtorName,AllGUI.debtorAddress,TCRSpecificGUI.debtorAccountType, TCRSpecificGUI.creditorAccountNumber,TCRSpecificGUI.proprietaryPartyType,AllGUI.debtorAgentName, AllGUI.debtorAgentCity,AllGUI.debtorAgentCountrySubDvsn,AllGUI.creditorAgentClearingSystemId, TCRSpecificGUI.purpose,TCRSpecificGUI.returnRejectReasonCode,TCRSpecificGUI.returnRejectReasonAdditionalInfo, AllGUI.payInstrument,AllGUI.typeOfCheck,AllGUI.passThruData,AllGUI.clearingAccount, AllGUI.jobId,TCRSpecificGUI.nachaTransactionCode,AllGUI.transactionType, TCRSpecificGUI.auxillaryOnUsIndicator,TCRSpecificGUI.batchTypeFromSourceSystem, TCRSpecificGUI.expressMailItem,TCRSpecificGUI.returnOccurance,TCRSpecificGUI.nameOfRMessageFile}); } }); </code></pre> <p>What is occurring there is that a GUI is being called first with the allGUI.createAllGUI() method. This is a JFrame with multiple JTextAreas for the user to fill out. Once the user clicks a confirm button on the first GUI a second one appears with more fields. When a user confirms each of the GUI's all the JTextArea information is saved into Strings and is then written into a JTable as a new row. (As seen above).</p> <p>The problem is that the logic above meant that the program would move to the dtm.addRow step even before the user had completed editing the text fields in the GUI. This means that the first row of the table would be totally blank (as the GUI fields had not yet been saved to strings).</p> <p>In short, the problem is that I needed some way to tell the program "Don't call the addRow code until the user has clicked the confirm button in the allGUI.createALLGUI() method second GUI.</p> <p>I finally found a solution. Since some users decided to mark this question as a "null pointer" duplicate I will just have to post my answer in the body here and then hopefully if the question is reopened I can post as answer.</p> <p>My solution was to move the addRow method into it's own class like this: </p> <pre><code>protected static void writeRow(){ dtm.addRow(new Object[]{TCRSpecificGUI.ntryName,AllGUI.bankTransCode,TCRSpecificGUI.endToEndId, AllGUI.transAmount,AllGUI.initiatingPartyId,AllGUI.initiatingPartySchemeName, AllGUI.debtorName,AllGUI.debtorAddress,TCRSpecificGUI.debtorAccountType, TCRSpecificGUI.creditorAccountNumber,TCRSpecificGUI.proprietaryPartyType,AllGUI.debtorAgentName, AllGUI.debtorAgentCity,AllGUI.debtorAgentCountrySubDvsn,AllGUI.creditorAgentClearingSystemId, TCRSpecificGUI.purpose,TCRSpecificGUI.returnRejectReasonCode,TCRSpecificGUI.returnRejectReasonAdditionalInfo, AllGUI.payInstrument,AllGUI.typeOfCheck,AllGUI.passThruData,AllGUI.clearingAccount, AllGUI.jobId,TCRSpecificGUI.nachaTransactionCode,AllGUI.transactionType, TCRSpecificGUI.auxillaryOnUsIndicator,TCRSpecificGUI.batchTypeFromSourceSystem, TCRSpecificGUI.expressMailItem,TCRSpecificGUI.returnOccurance,TCRSpecificGUI.nameOfRMessageFile}); } </code></pre> <p>leaving the original code like so:</p> <pre><code>addTransactionButton.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent ae){ AllGUI allGUI = new AllGUI(); allGUI.createAllGUI(); TCRSpecificGUI tcrGUI = new TCRSpecificGUI(); tcrGUI.getNtryName(); } }); </code></pre> <p>Finally in the last stage of my GUI where the user fills out the JTextFields I added this:</p> <pre><code>confirmButton.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent ae){ endToEndId=endToEndIdText.getText(); if(checkingButton.isSelected()){ debtorAccountType="Checking"; }else{ debtorAccountType="Savings"; } creditorAccountNumber=creditorAccountNumberCombo.getSelectedItem().toString(); proprietaryPartyType=proprietaryPartyTypeText.getText(); purpose=purposeText.getText(); returnRejectReasonCode=returnRejectReasonCodeText.getText(); returnRejectReasonAdditionalInfo=returnRejectReasonAdditionalInfoText.getText(); nachaTransactionCode=nachaTransactionCodeText.getText(); if(yesAuxillaryButton.isSelected()){ auxillaryOnUsIndicator="YES"; }else{ auxillaryOnUsIndicator="NO"; } batchTypeFromSourceSystem=batchTypeFromSourceSystemText.getText(); if(yesExpressButton.isSelected()){ expressMailItem="YES"; }else{ expressMailItem="NO"; } returnOccurance=returnOccuranceText.getText(); nameOfRMessageFile=nameOfRMessageFileText.getText(); Component component = (Component)ae.getSource(); Window window = SwingUtilities.windowForComponent(component); window.dispose(); TCRMainGUI.writeRow(); } }); </code></pre> <p>Note at the very bottom this line of code:</p> <pre><code>TCRMainGUI.writeRow(); </code></pre> <p>That calls the method to write a new row. </p> <p>So I now have a logic that 1. When a user clicks the create transaction button on the main JTable screen the first GUI class is opened. 2. Once the user fills out the fields and clicks confirm the values are saved to Strings and the next GUI opens. 3. Once the user fills out the fields on the second GUI and clicks confirm the values are saved and the method to add a row is called - The Strings are now populated so the row will be written with the values. </p> |

32,155,249 | 0 | <p>I would say the answer is: you can't. (or at least: you shouldn't). This is not what Webpack is supposed to do. Webpack is a bundler, and it should not be used for other tasks (in this case: copying static files is another task). You should use a tool like Grunt og Gulp to do such tasks. It is very common to integrate <a href="https://github.com/webpack/grunt-webpack">webpack as a grunt task</a> or as a <a href="http://webpack.github.io/docs/usage-with-gulp.html">gulp task</a>. They both have other tasks useful for copying files like you described. <a href="https://github.com/gruntjs/grunt-contrib-copy">grunt-contrib-copy</a> or <a href="https://www.npmjs.com/package/gulp-copy">gulp-copy</a>.</p> <p>For other assets (not the index.html), you can just bundle them in with webpack (that is exactly what webpack is for). <code>var image = require('assets/my_image.png');</code> But I assume your <code>index.html</code> needs to not be a part of the bundle, and therefore it is not a job for the bundler.</p> |

The PO will typically accept several user stories but reject one or two. At this point, the team no longer has a releasable build because the build consists of both the releasable stories and the unreleasable stories and there is no simple way to tear out the unreleasable stories. In addition, we do not want to just delete the code associated with the unreleasable stories because typically we just need to add a few bug fixes.</p> <p>How should we solve this problem? My guess is that there is some way to branch the build in such a way that either (a) each user story is on its own branch and the user story branches can be merged or (b) there is a way of annotating the code associated with each user story and creating a build that only has the working user story. But I don't know how to do either (a) or (b). I'm also open to the possibility that there are much easier solutions.</p> <p>I want to stress that the problem is not that the build is broken. The build is not broken -- there are just some user stories in the build that cannot be released.</p> <p>We are currently using svn but are willing to switch to another source control system if this would solve the problem.</p> <p>In addition to answers, I'm also interested in any books or references which address this question.</p> |

31,500,093 | 0 | <p>Basically this code relies on a little trick: if you seed the SHA1PRNG for the SUN provider and Bouncy Castle provider before it is used then it will always generate the same stream of random bytes. This is not always the case for every provider though; other providers simply mix in the seed. In other words, they may use a pre-seeded PRNG. In that case the <code>getRawKey</code> method generates different keys for the encrypt and decrypt, which will result in a failure to decrypt.</p> <p>Basically this horrible code snippet abuses the SHA1PRNG as a Key Derivation Fucntion or KDF. You should use a true KDF such as PBKDF2 if the input is a password or HKDF if the input is a key.</p> <p>That code snippet should be removed.

18,107,366 | 0 | <p>From the Apple iOS 6.0 release notes:</p> <p>"In general, Auto Layout considers the top, left, bottom, and right edges of a view to be the visible edges.

Changing the bounds origin of the superview does not change the position of the view.</p> <p>The UIScrollView class scrolls its content by changing the origin of its bounds. To make this work with Auto Layout, the top, left, bottom, and right edges within a scroll view now mean the edges of its content view."</p> <p>You can find the <a href="http://developer.apple.com/library/ios/#releasenotes/General/RN-iOSSDK-6_0/index.html" rel="nofollow">full notes here</a> and find the answer to your question in the section that I quoted from.

12,182,074 | 0 | Same or different xml namespaces? <p>In my project, there are lots of XML files of various sort, like XSDs, WSDLs, parameter maps etc. They all receive a generated namespace by the IDE, but the namespaces are not unique (across projects - elements with the same name get the same namespace) nor descriptive (or confusing - they all begin with "http://www.ibm.com/...", even though they define my own entities, not those of IBM). Namespace refactoring is necessary, then.</p> <p>My doubts are the following:</p> <p>1) Should every element have its own namespace, or should related elements share their namespaces? For instance, </p> <ul> <li>Should SOAP request and response messages belong to the same namespace, or should they have their own namespace?</li> <li>Should WSDL and related XSD use the same target namespace, or different?</li> </ul> <p>For example:</p> <pre><code>http://www.xarx.com/xmlns/TheProject/Administration/wsdl/StartProcess http://www.xarx.com/xmlns/TheProject/Administration/xsd/StartProcessRequest http://www.xarx.com/xmlns/TheProject/Administration/xsd/StartProcessResponse </code></pre> <p>or everything into</p> <pre><code>http://www.xarx.com/xmlns/TheProject/Administration </code></pre> <p>2) All generated namespaces that will be publicly visible must be corrected, sure. But what about the ones that are internal to the project - is their refactoring a waste of time? They might appear in the administration console or in logs, and wrong namespaces there could be misleading.</p> |
10,050,262 | 0 | <p><strong>Real problem in short:</strong> Circular library dependency between <code>arch</code> and <code>synergy</code>. Also, <code>base</code> actually wasn't linked to <code>common</code> library (in the CMakeLists.txt for <code>base</code>).</p> <p>Interestingly, this was caused by a configuration problem in the CMakeLists.txt files for the libraries. This had nothing to do with the CMakeLists.txt for the new <code>synergyd</code> application I had added.</p> <p>The problem was that I did not link the libraries to each other where new calls were added to classes in other libraries. However, it seems that there is now a problem with circular linking.</p> <p>For example, I could have added...</p> <pre><code>if (UNIX) target_link_libraries(arch synergy) endif() </code></pre> <p>... to CMakeLists.txt in the <code>arch</code> library, as <code>arch</code> now calls something in the <code>synergy</code> library. But this is invalid, since <code>synergy</code> already calls something in <code>arch</code>.</p> <p>Apparently this doesn't matter on Windows.</p> <p>I'm not quite sure though what caused this to start happening, as it's all old code that has been compiling fine before, and still does in other applications. I suspect most likely something to do with the recent removal of boiler plate from CArch, rather than something that CDaemonApp is doing (or maybe even a combination of both).</p> <h1>Update</h1> <p>Just in case anyone cares ;-) -- I think it is something to do with the relation between the lousy circular library dependency between <code>arch</code> and <code>synergy</code>, combined with the fact that <code>CDaemonApp.cpp</code> wasn't including <code>CApp.h</code> -- meaning that it was included at some other point, causing the weird undefined reference errors.</p> <p>To solve this properly, I have removed the circular dependency, which appeared to be the core of the problem.</p> <h1>Update 2</h1> <p>The code now fully compiles, hurrah! </p> <p>I was still seeing one last error (the topic of this question):</p> <pre><code>[ 90%] Building CXX object src/cmd/synergyd/CMakeFiles/synergyd.dir/synergyd.o Linking CXX executable ../../../../../bin/debug/synergyd ../../../../../lib/debug/libbase.a(CLog.o): In function `CLog::insert(ILogOutputter*, bool)': /home/nick/Projects/synergy/branches/1.4/src/lib/base/CLog.cpp:213: undefined reference to `kAppVersion' collect2: ld returned 1 exit status make[2]: *** [../../bin/debug/synergyd] Error 1 make[1]: *** [src/cmd/synergyd/CMakeFiles/synergyd.dir/all] Error 2 make: *** [all] Error 2 </code></pre> <p>This was simply caused by the <code>base</code> library not linking to the <code>common</code> library.

Zed may be malicious, or Zed may be the victim of a CSRF. However, your question is only that B knows that the request is coming from A. A can validate the input and take appropriate action.

After that the message is deleted from the message collection.</p> <p>If I execute the python script manuallly everything works fine, but if Cron runs it the user will not be updated but the message will be deleted.</p> <p>The mongodb server is 2.4.10, I know it's old but it's the latest verion which runs on a raspberry pi 2, afaik.
